Match the hormones given in Column A with their deficiency disease given in Column B.

Column A	Column B
(a) Adrenal hormone	(i) Dwarfism
(b) Growth hormone	(ii) Goitre
(c) Thyroxine	(iii) Diabetes
(d) Insulin	(iv) Salt imbalance

The correct option is (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii).

Let us analyze the deficiency diseases associated with each hormone step-by-step:

(a) Adrenal hormone (Aldosterone / Corticoids):
The adrenal cortex produces hormones such as aldosterone, which regulates the balance of water and salts (electrolytes like sodium and potassium) in the body. A deficiency or imbalance in adrenal hormones leads to a severe salt imbalance (and condition such as Addison's disease).
Therefore, (a) matches with (iv).

(b) Growth hormone:
Growth hormone (GH) is secreted by the anterior pituitary gland and stimulates physical growth and development. Hyposecretion (deficiency) of growth hormone during childhood leads to stunted growth, known as Dwarfism.
Therefore, (b) matches with (i).

(c) Thyroxine:
Thyroxine is secreted by the thyroid gland, which requires iodine for its synthesis. A deficiency of thyroxine or dietary iodine causes swelling of the thyroid gland in the neck, a condition known as Goitre.
Therefore, (c) matches with (ii).

(d) Insulin:
Insulin is produced by the beta cells of the pancreas and regulates blood glucose levels by helping cells absorb glucose. Deficiency of insulin results in high blood sugar levels, causing Diabetes (specifically Diabetes mellitus).
Therefore, (d) matches with (iii).

Combining all the correct pairs, we get:
(a) - (iv)
(b) - (i)
(c) - (ii)
(d) - (iii)
